A number of explosive devices were located at Dover City Park on Memorial Day weekend by a member of the Dover Marshals Office (DMO).

According to a DMO press release issued Tuesday afternoon, Deputy Marshal Lt. David Dalrymple located a number of devices in the park at around 10 p.m. Sunday.

“The park was quickly secured, and investigators responded to the scene,” the press release stated. “A total of at least eight devices were found in the park; two had already exploded, four had malfunctioned and had become inert, and two were potentially still explosive. The two ‘live’ devices were destroyed at the scene by the Conway Fire Department Bomb Squad.”

No injuries were reported and no estimate of any damage to park property was included in Tuesday’s report.

The DMO reported the investigation is ongoing and several leads have been developed.

According to the report, the devices were “not sophisticated and can be made from common household items and plastic drink bottles.

While they are small devices, they are considered powerful enough to produce significant property damage or serious personal injury or death.”

The DMO cautioned that the making of such devices should not be made “for fun” as they are very dangerous and illegal to produce or possess.
